' WHJIIIAM GLIMIE, OF TORONTO, ONTARIO, CANADA.

GAS PRODUCER.

Original application filed June 15, 1922, Serial No. 568,523, and in Great Britain June 15, 1821. Divided and. this application filed November 24, 1924. Serial No. 751,926.

This application for a patent is a divisional application from my copendlng application Serial N 0. 568,523, filed 15th June, 1922. Y

This invention has reference to improvements in and relating to gas producers of the class in which a rotatable grate or air blast cone built up of a plurality of superimposed rings having slots or air openings formed in same is arranged centrally in'relation to a rotatable ash pan provided with a scraper blade or scoop adapted to scoop out and dis- I charge the ashes over the wall of the pan.

This invention comprises a gas producer 1:; provided with an air blast cone consisting of a plurality of superimposed rings having slots or openings between same and of a double kneed formation. The said rings are secured to an angled frame fitted to a base plate adapted to rotate and provided with water seals. Projecting ribs are provided on the angled surface of the cone and a rotatable ash pan having a projecting knife is located below and around the cone.

In order that my said invention and the manner of carrying the same into effect or practice may be properly understood I have hereunto appended one sheet of explanatory drawings in which:

Figure l is a sectional elevation of the lower end of a gas producer illustrating the air blast cone and ash pan as constructed according to this invention.

Figure 2 is a plan view correspondingto as Figure 1. r I

Referring to these drawings o The gas producer or generator may consist of two cylindrical casings 1 and 2 arranged vertically and concentrically one within the 4.0 other so that a water jacket space 3 is formed between them. This space 3 is closed at its bottom end. The bottom end of the inner cylindrical casing 1 is open. Cent-rally at the bottom end of the inner casing an air blast cone is arranged.

Accordin to this invention this cone is built up 0. rings 4 secured to a suitable frame which consists of bars 5 arranged at an angle in such a manner that the outer surfaces of the rings 4 form the cone surface. The rings 4 are spaced at a suitable distance apart so that slots or openings 6 are formed to permit the air blast to pass from the interior of the cone into the generator.

The rings 4 are of double kneed or double angled formation in cross section and are provided on their outer surfaces with angled pro ecting blades, bars or flanges so'that when assembled the cone surface is formed with angled ribs 23. These bars 23 may project beyond the upper and lower edges of the rings 4 so that the angled ribs 23 may be continuous from top to bottom of the cone. Preferably these ribs are arranged in a spiral manner around the cone.

The base'of the frame carrying the rings 4 and forming the cone base consists of a circular plate 7 having centrally a downwardly projecting vertical tube or trunk .8, the lower end of which is provided with a. water seal 9 and is in free communication with the main air supply conduit 10. The base plate 7 of the cone is mounted upon ball or roller bearings 11 carried by a suitably shaped supportmg structure 12.

The cone is adapted to rotate upon the ball or roller bearings 11 preferably by means of a worm wheel 13 mounted upon the vertical trunk 8 and driven by a suitably mounted worm 14. Below the two concentric casmgs l and 2 an ash receiver or pan is arranged. This pan consists of a plate 15 which extends annularly and radially from the supporting structure 12 of the cone outwards beyond the outer surface of the generator and is supported upon ball or roller bearings 16 carried by the said supporting structure 12.

The periphery or outer edge of this plate 15 is provided with a wall or rim 17 preferably angled outwards so that the plate 15 and the mm 17 form a pan. Between the base of the cone and the pan a water seal may be arranged preferably by means of an annular downwardly hanging wall 18 which dips into a trough 19 provided between two upright walls 20. The an is adapted to be rotated as desired preferably at intervals of time by means of worm and worm wheel gearing 21 suitably arranged below the pan. An annular downwardly hanging plate or the like 22 dippinghinto the pan is fitted to the lower end of t e cylindrical casings so as to form an outer water seal. A scraper blade, scoop or the like 25 is arranged so that as the pan is rotated the ashes are scooped out of the pan and discharged over the outer wall of same.

The pan and the cone may be rotated in the same or in opposite directions.

If desired an upwardly projecting blade or cutter 24 may be fitted to the bottom of the pan so that as the pan is rotated the knife will prevent the formation of clinker between the lower edge of the cone and the inner wall of the generator.

Preferably this rotatable air blast cone with the project-ing ribs operates iii-conjunction with that type of fuel rake which is adapted to press upon and rake the top surface of the fuel.

In operation the fuel moves downwards as it is consumed, and the action of the top pressing rake, rotatable air blast cone with the ribs (which are preferably of spiral formation to draw down the exhausted fuel) and the rotatable ash pan with the projecting knife and automatic discharge scoop prevents the fuel from forming into cavities, holes and passages which are bridged by clinker and through which unconsumed fuel may descend into the ash zone.

The inner of the two concentric casings is preferably shorter than the outer one so that the water space between the two casings 0 ens into a steam space arranged between t e tops of the two casings. The upper end of the two casings are each closed by a plate.

I claim 1. A rotating grate, for use in a gas producer, having the form of a cone which consists of a plurality of independent rings superposed one above another, each ring comprising a horizontally disposed body portion having a circular angularly disposed depending flange adjacent its outer edge and a circular angularly disposed upstanding flange adjacent its inner edge, the said flanges being disposed parallel one with the other throughout their respective circumferences; a skeleton frame within said series of rings and supporting the individual rings of the series in a manner to form an air passage between the respective flanges and body portions of adjacent rings of the series; a rotatable base plate for supporting said skeleton frame; and a cap element forming the apex of said cone.

2. A rotating grate, for use in a gas producer, having the form of a cone which consists of a plurality of independent rings superposed one above another, each ring comprising a horizontally disposed body having a circular angularly disposed depending flange adjacent its outer edge and a circular angularly disposed upstanding flange adjacent its inner edge, the said flanges being disposed parallel one with the other throughout their respective circumferences and the angular faces of said superposed flanges being in contiguous alignment to form regular conical surfaces; a conical skeleton frame within said series of rings and supporting the individual rings of the series in a manner to form an air passage from the interior of said cone to the-outer face thereof between the respective flanges and body portions of the adjacent superposed rings of the series; a rotatable base plate for supporting said skeleton frame; and a cap element forming the apex of said cone.

3. A grate, for use in a gas producer, having the form of a cone which consists of a plurality of independent rings superposed one above another, each ring comprising a horizontally disposed body portion having a circular angularly disposed depending flange adjacent its outer edge the flanges of the successively superposed rings being in contiguous parallel alignment to form a regular conical surface for said grate; and a frame within said series of rings and supporting the individual-rings of the series in a manner to form an air passage between the respective flanges and body portions of ad jacent rings of the series.

4. A rotating grate, for use in a gas producer, having the form of a cone which consists of a plurality of independent rings superposed one above another, each ring comprising a horizontally disposed body having a circular angularly disposed depending flange adjacent its outer edge and a circular angularly disposed upstanding flange adjacent its inner edge, ,the said flanges being disposed parallel one with the other throughout their respective circumferences; and means supporting the individual rings of the series in a manner to form an air passage between the respective flanges and body portions of adjacent rings of the series the said flanges functioning as baflies for the air passing through said air passages.
